Effect of reconstituted method on shear strength properties of peat [PDF]

, 2017
Peat is an organic soil contains more than 75% organic content. Shear strength of the soil is one of the most important parameters in engineering design, especially during the pre-construction and post-construction periods, since used to evaluate the ...

A Surrogate Model for Stability Assessment of Two‐Layered Cohesive Slopes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper introduces a novel surrogate model for rapid stability evaluation of two‐layered cohesive slopes under undrained conditions. The model eliminates the need for iterative calculations and slip surface searches, allowing for fast and accurate stability assessments without reliance on advanced numerical tools. The formulation is derived

Undrained shear strength in dependence on the quantity of free water and firmly adsorbed water in fully saturated clays [PDF]

, 2012
The article describes the dependence between the undrained shear strength of fully saturated cohesive soils, the quantity of intergrain water and mineralogical properties of soils on the basis of theoretical analysis and practical tests on monomineral ...

Undrained Shear Strength of Unsaturated Soils under Zero or Low Confining Pressures in the Vadose Zone

Vadose Zone Journal, 2018
In geotechnical engineering practice, many projects such as stability analysis of slopes or trenches and pavement design involve soils in vadose zones at shallow depths, where soils are under unsaturated conditions. For these types of projects, undrained

CPT‐Based Probabilistic Characterization of Undrained Shear Strength of Clay [PDF]

Advances in Civil Engineering, 2020
Applying random field theory involves two important issues: the statistical homogeneity (or stationarity) and determination of random field parameters and correlation function. However, the profiles of soil properties are typically assumed to be statistically homogeneous or stationary without rigorous statistical verification.

Evolution of Pore Fluid Pressure in an Accretionary Outer Wedge Over Megathrust Earthquake Cycles: The Northern Cascadia Example

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Variations of Undrained Shear Strength of EPB Mud and a Calculation Model Based on Consistency Index

Advances in Civil Engineering
If earth pressure balance (EPB) shields are used for tunneling in clayey soils, dispersants are often applied to condition the mud. For the conditioned mud, the undrained shear strength is a key indicator determining the shield tunneling operational ...

Shear strength model for overconsolidated clay-infilled idealised rock joints [PDF]

, 2008
Saturated infilled joints can contribute to the instability of rock masses during undrained shearing. This paper reports an experimental investigation into the effect of the overconsolidation of infilled rough joints on undrained shear behaviour.
